Definitions

  • the invention relates to a drive system, the one DC link converter, a motor and a holding brake has, the holding brake mechanically and the converter is electrically connected to the motor.
  • Such a drive system is used in drive applications used in which the motor is in its position at a standstill must be recorded. These applications include e.g. Lifts and cranes.
  • the holding brake is assigned their actuation is a contactor, an external DC voltage supply and a brake control unit.
  • This external DC voltage supply is electrically parallel to the connections the holding brake switched, being in one connection the contactor is switched.
  • This contactor is by means of controlled the brake control unit, this brake control unit a brake signal from a higher-level control device is fed.
  • the invention is based on the object, the known drive system to develop such that their remaining Disadvantages are eliminated.
  • this is a connection the holding brake not by means of a switching device with the minus connection the voltage intermediate circuit of the converter connected, but directly to a midpoint connector this voltage intermediate circuit.
  • FIG. 1 shows a voltage intermediate circuit converter with 2, with 4 a motor, in particular a synchronous motor, with 6 one Holding brake and designated 8 a switching means. From the DC link converter are because of the clarity only the voltage intermediate circuit 10 and the load-side converter 12, which is also referred to as an inverter. In the case of a standard converter, the converter shows on the line side still an uncontrolled converter, which as Rectifier is referred to. The one in this illustration shown voltage intermediate circuit 10 has no midpoint connection on. This is characterized by only one Electrolytic capacitor 14 is shown in the equivalent circuit diagram. With this voltage intermediate circuit 10 is the inverter 12 tied on the DC side, with AC side the motor 4 is connected to the inverter 12.
  • the holding brake 6 is connected to the star point connection 16 of the motor 4 and with its second connection by means of the switching means 8 with the minus connection 18 of the Voltage intermediate circuit 10 knotted.
  • switching means 8 is a switchable semiconductor switch is provided in this Embodiment part of the voltage intermediate circuit converter 2 is. This switching means 8 can also outside of the converter 2 may be arranged, in which case the minus connection 18 of the voltage intermediate circuit converter 2 accessible have to be.
  • the switching means 8 is actuated, which closes the brake circuit. Thereby there is a voltage at the holding brake 6 which is approximately corresponds to half the DC link voltage. This In normal engine operation, tension arises from the fact that Potential of the neutral point connection 16 is zero on average and the potential of the negative terminal 18 is negative. Without this switching means 8 would constantly this voltage on the Holding brake 6 are applied, whereby the motor 4 never released would. This embodiment is preferred when the voltage intermediate circuit 10 has no midpoint connector.
  • FIG. 2 shows the equivalent circuit diagram of a second embodiment of the drive system according to the invention shown in more detail.
  • This embodiment differs from the embodiment according to FIG 1 in that the voltage intermediate circuit 10 now has a center connection 20. This is illustrated by the voltage intermediate circuit 10 has two electrolytic capacitors 14, which are electrically in Series are connected. Otherwise this embodiment corresponds that of FIG. 1
  • the mean potential of the Star point connection 16 at the potential of half the intermediate circuit voltage.
  • the midpoint connector 20 of the Voltage intermediate circuit 10 is at the potential of half DC link voltage. This is due to the holding brake 6 on average no voltage during normal engine operation on.
  • the string voltages of the Motors 4 generated in such a way that each phase voltage with a DC voltage is applied.
  • This DC voltage is called offset voltage and has one each Value that corresponds to a release voltage of the holding brake 6.
  • the potential is at the star point connection by means of the offset voltages 16 higher than that by the value of this offset voltage Potential at the midpoint connection 20 of the voltage intermediate circuit 10 of the converter 2. This offset voltage as release voltage on the holding brake 6.
  • Motors 4 with integrated holding brake 6 are commercially available. Will such a combination in an inventive Used drive system, so the electrical Connection of a connection of the holding brake 6 to the star point connection 16 of motor 2 must be wired internally. This means that only four lines would have to be between converter 2 and the motor 4 with integrated holding brake 6.
